+* Thu Aug 15 2019 Paul Howarth <paul@city-fan.org> - 0.44-1
+- Update to 0.44
+  - Replaced the use of B with XString if it is installed; the latter is much
+    smaller and provides the one subroutine from B we cared about (based on
+    GH#15)
+- Use %%{make_build} and %%{make_install}

 * Fri Jul 26 2019 Fedora Release Engineering <releng@fedoraproject.org> - 0.43-5
 - Rebuilt for https://fedoraproject.org/wiki/Fedora_31_Mass_Rebuild
